SP.RING-BED.

SPECIFICATION forming part of Letters Patent No. 729,021, dated May 26,1903.

Application filed May 17,1902. SerialNo-107.750. (No model- To all whom,it may concern:

Be it known that we, FREDERICK J. VAN OISE and WILLIAM C. VAN OISE,citizens of the United States, and residents of Mayville, in the countyof Chautauqua and State of New York, have invented a new and usefulSpring- Bed, of which the following, taken in connection with theaccompanyingdrawings,isafull, clear, and exact description.

Our invention relates to springs for beds, couches, chairs, and otherarticles on which springs are used; and our main object is to do awaywith the use of cords and materials which are easily abrasive andsubstitute our coiled-wire connections and improved locked connection orclip both for connecting the spring-centers, their outer rims, orwherever a permanent spring connection is desired to hold thecone-springs in shape, and also to provide a strong inetallic base orframe for our spring.

Our present construction is an improvement on a connection or clip asshown in a former patent, No. 641,660, of January 16, 1900, to WilliamC. Van Cise.

In the drawings, Figure 1 is a plan view of part of a lounge-springhaving our improvement. Fig. 2 isaside elevation showing form oflocking-clip and a section of spiral spring in the clip, and Fig. 3 is aperspective view of the under side of the clip and spiral. Fig. 4 is asectional view of iron bed-rails, the arched metal cross-piece for thespring, and hangers for suspending the base on the rails. Fig. 5 is asectional view of a portion of a double-cone spring and woodcouch-frame. Fig. 6 is a detail of single-cone spring as attached tometal base. Figs. 7, 8, and 9 show modifications of locking-clip.

Similar numerals refer to corresponding parts.

Numeral 10 is a single-cone spring, and 11 is a double-cone spring.Spring 10 is used mostly for bed-springs, and spring 11 is used more forlounges, seats, and the like, though they may be used interchangeablyfor these purposes.

Numeral 12 is our locking connection or clip,being made doubleinstead ofsingle,as in the former construction, and having holes 13 punchedthrough both sides at the angle of coil of the spiral coil 14:, so thatcoil 14 may be turned through the four holes in clip 12, locking theclipfast. We have found that the single clip as formerly made would pry0E from the wire undergreat strain, and have therefore made our clipundetachable, the only method of removal being by turning coil 14 out ofholes 13. We find that this locked clip acts equally well for connectingthe center of double-cone springs, like 11 in Fig. 5. This is speciallyapplicable in lounge-springs, where an open and highly-resilient springis desired to make an easy seat. Such a spring, however, is hard to holdin place, and it has been customary to tie such springs with strongcords. The cords, however, are easily abraded and out by the wire andbreak in a comparatively short time. The lounge must then be sent tothe'shop'for repairs. Our spiral coil connect-ion and .locking clipconnects the spring centers and is stapled to the loungeframe 29, as at15. The coil 14 allows the spring to give, yet draws it back to place atonce when released, and is also used for connecting the tops, bottoms,or centers of rows of springs. It will be seen, therefore, that no cordsare necessary. The connections are locked to place, and no matter howhard the usage accorded them the springs cannot get out of place. Spiralcoil connections 1 1 are shown attached to both the bed-frame and abinding-wire in Fig. 1. It is also apparent that coil '14 would serve agood purpose if its ends were unattached after passing through the outerclips, since the spiral angle of the coil locks the 'coil fast in theclips, so that it cannot be removed except by turning out of the holes,and a slight twist of the end will stop even this means of removal. Ittherefore forms a complete connection for sp ings in which it is notdesirable to attach to outside support or binding-wire.

Numeral 16 is the oute angle-iron rim of my iron frame or base for thespring. N umerals 17 17 are flat iron cross-bars which are riveted toiron rim 16 and on which the springs are fastened by punching holes 18near the upper edge and running binding-wires 19 over the bottomspring-wire 20 and through holes 18, the end of wire 19 being fastenedin iron 16, as at 21 in Fig. 5. We use a single binding-wire for holdingthe bottom of a singlecone spring, as at 22 in Fig. 4, and twobinding-wires, as at 23, for holding a double-cone spring. We punch theholes 18 near the upper edge of cross-bars 17 larger than would benecessary for the insertion of cross-wires 19 for a purpose. It isan oldand well-known fact that punching the holes 18 near the edge of barswill curve the bars to that side,'and of course the larger the holes aremade the greater the curve, and the holes 18 must be punched and notdrilled to curve bar 17. By turning this curve upward in the frame forthe bed-bottom an arched and much stronger construction is given tothese cross-bars 17, as shown in Fig. 4, without added expense. Across-bar 17 supports each row of springs, and bindingwires 19 run atright angles thereto through said bars and springs, attaching thesprings firmly on the bars. The bedbottom is supported on the side rail24 of the bedstead by a number of hooks or hangers 25 on each side.

The modification 26 of locking clip or link 12 (shown in Fig. 7) is madethe same as clip 12, with the exception that notches 13' are cut inplace of holes 13 to receive the spiral connecting-wire 14. The notchesserve the purpose in certain cases but we usually prefer holes'13, sincethey form a complete lock.

The modification 27 of locking clip or link 12 (shown in Fig. 8) is alesser spiral than 14, which is bent to form a link, as shown, and

' spiral 14 is turned through coils of link 27,

locking the ends and opposite sides firmly to coil 14. This form ofconnecting-clip is advantageous where easy or exceedingly resilientsprings are desired, since it is apparent that the spiral double link orclip 27 will spring or give the same as coil 14.

The modification 28 of locking clip or link 12 (shown in Fig. 9) is asimple link chain, such as is common for connecting the conesprings inspring-beds. 1 We turn our spiral coil 14 through the openings in thelinks, thus looking all fast and forming a fair substitute for clip 12.

Our reason for preferring clip 12 is its cheapness, durability,security, and the ease with which it can be adjusted on the center orouter coils of a cone-spring.

It is apparent that the bottom coils of the double-cone springs 11 couldhe stayed or held by clips 12 and spiral 14, the same as the top coils,as shown in Fig. 5, and that if the centers and outer ends of thecone-springs 11 were so stayed it would form a serviceable spring formany purposes Without the iron base.

The arching orupward curving of the crossbars 17 serves a doublepurpose, besides greatly strengthening the cross-bars, as is apparent inall arched constructions. It so forms our metal base that it does notneed support except under the side bars 16, and if level supports aresupplied for sides 16 the bed-base will rest firm and solid.

We claim as new-- 1. A spring-bottom for beds having conesprings, doublemetal clips attached to the central or outer coils of said cone-springs,openings in said clips, suitable wire stays to engage said openings insaid clips.

2. A spring-bottom for beds having conesprings, flat metal links forconnecting said cone-springs, openings in said links at an anglesuitable to receive a spiral coil, and coiled wire stays which passthrough said openings and lock said links.

3. A spring-bottom for beds having conesprings, double metal clips orlinks for attachment to the central or outer coils of said cone-springs,openings in said clips to receive spiral stays, spiral stays which passthrough said openings and lock said clips, a suitable frame for saidbeds, the ends of said spiral stays secured to said frame, substantiallyas and for the purpose specified.

In testimony whereof we have signed our names to this specification inthe presence of two subscribing witnesses.
